Water-soluble fluorescent probe and nanoparticals with aggregation-induced emission effect for ovarian cancer and preparation method and use thereof

Disclosed are a water-soluble fluorescent probe and nanoparticles with an aggregation induced emission (AIE) effect and preparation methods and the application. The fluorescent probe molecule includes one imidazole ring substituted by two methoxyphenyls and one phenyl and two quaternary ammonium salt structures. It has good dispersion in water, may form micelles. It has the characteristics of AIE effect and a large Stokes shift etc. It is suitable for fluorescence detection. Under the induction of lysophosphatidic acid, the probe can be self-assembled so as to aggregate and generate yellow fluorescence. Lysophosphatidic acid may be quantitatively analyzed by measuring the intensity of emitted fluorescence.
